Three adult dogs were used in this experiment to investigate the usefullness of baked dental root tips for bone replacement materials. In the experimental method, baked dental root tips (800℃,20 minutes) of the human devitalized teeth and hydroxyapatite (HA) granules were respectively filled in the mandibular bone of the dog. Tissue specimens were taken 1, 3 and 5 weeks post operatively for observation under the light microscope.
1. In the case of filling of baked dental root tips, osseous addition occured 3 weeks after operation. In the case of filling of HA granules, osseous addition occured 1 week after operation.
2. In the both cases, osseous additoion were incessantly observed 5 weeks after operation.
3. The baked dental root tips may be useful as bone replacement materials.
